About Used 2013 Mac Curtainside Trailers
A buyer should pay close attention to the base trailer under the curtain system. Common 2013 Mac specs include aluminum floors, aluminum bulkheads, aluminum side rails, and 72K beam ratings, which help keep tare weight down while maintaining useful payload capacity. Suspension setup matters too. Many units in this category use Hendrickson Intraax air ride with a spread axle setting around 10 feet 2 inches. Check kingpin setting, typically around 30 inches, along with crossmember spacing, often 16 inches on center, because these details affect load placement, ride quality, and long-term durability in steel and building products service.
Curtainside buyers should inspect the tarp system as carefully as the trailer itself. Rear roll or roll-up operation, tarp track condition, bow alignment, rear closure fit, and fabric wear all affect how well the trailer protects cargo and how much downtime you may see. On Mac curtainside trailers, it is also common to see coil package equipment, multiple tiedown points, pipe spools, chain storage, and nailing strips. If you haul coil steel or heavier concentrated loads, make sure the coil package is complete and verify floor condition around the load zone. If your freight mix is more palletized or crated cargo, focus on side opening clearance, interior width and height, and how quickly the curtain system can be opened and secured at the dock or jobsite.
Mac has a strong reputation in aluminum trailer construction, and a used 2013 model can be a practical option for fleets that want lower empty weight without moving away from specialized flatbed freight. The best value usually comes from matching the trailer to the lane and commodity. Air ride helps protect finished goods and sensitive freight. Aluminum wheels, LP24.5 or 22.5 tire setups, Jost two-speed landing gear, and well-kept lighting and brake components all matter in day-to-day operating cost. A careful inspection should include suspension wear, brake percentage, tire life, floor integrity, tarp frame operation, and signs of corrosion or damage around the bulkhead, side rails, and rear structure.
Frequently Asked Questions
What is a 2013 Mac curtainside trailer typically used for?
A 2013 Mac curtainside trailer is commonly used for freight that benefits from flatbed-style loading but still needs protection from rain, road grime, and UV exposure. Typical cargo includes steel products, palletized building materials, machinery, packaged industrial freight, and some finished goods. Because the side curtain or Conestoga-style cover opens wide, these trailers work well for shippers that load by forklift from the side or by crane from above.
Are many 2013 Mac curtainside trailers actually aluminum flatbeds with Conestoga systems?
Yes. In this category, many 2013 Mac units are aluminum flatbed trailers equipped with a rolling tarp system such as a Conestoga. That means the core trailer has flatbed construction, with features like aluminum flooring, tiedown hardware, bulkheads, and coil package options, while the movable cover adds weather protection. For buyers, it is important to evaluate both the flatbed structure and the tarp system as separate but equally important components.
What specs matter most when comparing used Mac curtainside trailers?
The most important specs usually include trailer length and width, suspension type, axle spread, beam rating, kingpin setting, floor material, and tiedown configuration. On many 2013 Mac trailers, buyers will see 48-foot by 102-inch dimensions, air ride suspension, 72K beam ratings, and aluminum construction. Beyond published specs, the condition of the tarp frame, fabric, brakes, tires, crossmembers, and floor often matters more than small differences in equipment.
Is air ride suspension important on a curtainside trailer?
Air ride is a major advantage for many curtainside applications because it helps reduce cargo shock and improves ride quality for sensitive or high-value freight. It is especially useful for finished goods, crated machinery, and palletized materials that can shift or suffer damage from harsh suspension movement. On used equipment, the key is not just having air ride, but confirming the suspension components, bushings, airbags, shocks, and alignment are still in sound operating condition.
What should I inspect first on a used 2013 Mac curtainside trailer?
Start with the tarp system, floor, suspension, brakes, and tires. The curtain or Conestoga assembly should open and close smoothly, seal properly, and show no major tears, bent bows, or track damage. Then inspect the aluminum floor and crossmembers for signs of concentrated-load damage, especially if the trailer has hauled steel or coil freight. After that, review brake wear, tire condition, landing gear operation, and structural areas such as the bulkhead, side rails, and rear frame for repairs, corrosion, or impact damage.
